Definitions

  • the invention relates to a contact element for electrical conductors according to the preamble of claim 1.
  • a connecting piece is known from DE 27 26 742 A1, in which the contact element is made of plastic.
  • Contact elements for electrical conductors are required, in particular, for components in telecommunications technology, such as terminal strips and isolating strips, wire connectors, printed circuit boards and the like.
  • the contact element is regularly formed from an electrically conductive, metallic material and inserted into the component consisting of an insulating material.
  • Thermoplastic materials are regularly used as insulating materials in connection and separation strips and wire connectors, and paper-based boards or glass fiber-reinforced synthetic resins are impregnated with printed circuit boards in synthetic resin.
  • the disadvantage here is that two components are regularly necessary, namely a base body made of insulating material and the metallic contact element inserted into it. As a result, the manufacture and assembly of the known contact elements for electrical conductors are expensive and complex.
  • the invention is therefore based on the object of creating a contact element of the generic type which is simple and inexpensive to manufacture and which simplifies and reduces the cost of producing and assembling the components using the contact elements.
  • the contact surface of the contact element is formed from an insulating material, preferably the insulating material of the component itself, and provided with metallized surfaces.
  • the contact element can preferably be formed in one piece simultaneously with the component from a uniform insulating material, the contact surface subsequently being provided with a metallized surface.
  • the contact element according to the invention is particularly suitable for use in printed circuit boards in which the contact element according to the invention can be molded in one piece with the printed circuit board.
  • the contact element according to the invention can also be used with advantage in the formation of wire connectors. In this case, a stripped conductor can be clamped between tapered contact surfaces.
  • the contact surfaces are provided with cutting edges forming the contact slot, which are formed from the insulating material and provided with metallized surfaces and which cut in the sheathing when a non-stripped conductor is pressed in, and thus make electrical contact with the conductor core with the metallized surfaces.
  • the contact element 1 for electrical conductors 2, in particular for cable wires in telecommunications technology, consists of two electrically conductive contact surfaces 4, including a contact slot 3, which are formed from an insulating material 5 and are provided with metallized surfaces 6.
  • the insulating material 5 is formed into block-like elevations 7, between which the V-shaped contact slot 3 is formed, the base 8 of which is flattened.
  • the side surfaces of the V-shaped contact slot 3 and the adjacent regions of the elevations 7 are provided with the metallic surfaces 6 to form the contact surfaces 4.
  • the metallized surfaces 6 are formed by vapor deposition or electrolytic deposition of conductive metallic material on the surfaces of the insulating material 5.
  • the conductor core 11 of the conductor 2 is stripped and clamped between the contact surfaces 4 of the conically tapering V-shaped contact slot 3. In this case, an electrical contact connection is created between the conductor core 11 of the conductor and the metallic surface 6, which is led to a conductor connection point in a manner not shown.
  • the elevations 7 are located on a carrier 9, which can be formed from a printed circuit board.
  • a carrier 9 which can be formed from a printed circuit board.
  • 3 several, each having a contact slot 3 between including contact surfaces 4 on a support 9 are arranged side by side, the contact surfaces 4 of adjacent contact slots 3 being provided with electrically separated metallized surfaces 6, 6 ', 6 ⁇ , 6 ′′′.
  • This contact element 1 can also be arranged on a printed circuit board formed by the carrier 9.
  • the elevations 7 of the carrier 9 forming the printed circuit board are formed in one piece with the carrier 9 forming the printed circuit board.
  • the previously described contact elements of the first embodiment require the conductors 2 to be stripped beforehand and thus the conductor core 11 to be exposed, which is clamped in the contact slot 3 of the contact elements 1.
  • the side surfaces of the contact slot 3 can hold the conductor core 11 by frictional contact.
  • a soldering process can also take place between the conductor core 11 and the metallized contact surface 4.
  • the contact elements 1 described so far are used essentially in printed circuit boards which are molded from plastic, the elevations 7 being able to be molded at the same time.
  • the metallized surfaces 6 are produced by electroplating or the like and can be produced simultaneously with the formation of the conductor tracks on the circuit board.
  • the embodiments of the contact element described below do not require stripping of the conductors 2, but form insulation displacement contact elements to which the conductors 2 can be connected without stripping.
  • the conductor 2 is formed from the insulating material 15 on the contact surfaces 14 to cut the sheathing 12 opposed cutting edges 13 provided with metallized surfaces 16. These are triangular in cross section and are formed in one piece with the insulating material 15 of the carrier 19 forming the contact element. Since the triangular cutting edges 13 are formed in one piece from the insulating material 15 of the contact element, the cutting edges 13 can be designed to be resilient to a small extent.
  • these can also be formed from cut-out, triangular plastic tabs. In any case, it must be ensured that the triangular cutting edges 13 abut the conductor core 11 in a clamping / resilient manner after cutting in the sheath 12 of the conductor 2.
  • the metallized surfaces 16 come into contact with the conductor core 11 so that an electrical contact connection can be established.
  • undercuts 18 can be formed in the elevations 17 between the cutting edges 13, which are integrally formed from the insulating material 15 of the carrier 19.
  • the opposite cutting edges 13, which form the contact surfaces 14, are formed within channels 20 embedded in the insulating material 15, into each of which a conductor 2 is inserted.
  • the metallized surfaces 16 of both channels 20 are conductively connected to one another, so that a wire connector is created here.
  • cutting knives 21 are inserted, which at the same time separate the conductors 2 when they are pressed into the cutting edges 13 by means of a tool (not shown in more detail).
  • plug tongues 22 can additionally be formed from the insulating material 15 of the contact element.
  • FIG. 8 shows an enlarged detail of two opposite cutting edges 13 which are in electrical contact with the conductor core 2 by cutting the sheath 12 of the conductor 2 with its metallized surfaces 16.
  • the contact surfaces 24 are formed as metallized cutting edges 25 of the contact element, the cutting edges 25 being associated with pre-cutting edges 27 with a V-shaped opening angle 26.
  • the contact element according to the third embodiment is intended for insertion into the plastic body of terminal strips or isolating strips or plugs or can be formed in one piece with them.
  • the contact surfaces 24 of the cutting edges 25 are provided with metallized surfaces 28. These lead to a connection point, not shown.
  • a contact element according to the third embodiment can also have two or more contact slots 23, the contact surfaces 24 of which are connected to one another via common metallized surfaces 28.
  • the fourth embodiment of the contact element shown in FIGS. 13 to 16 comprises a printed circuit board 30, in the two edge areas of which comb-like clamping slots 31 are made, which are elongated rectangular in cross section. At least the inner region of the clamping slots 31 is provided with a metallized surface 32, which are connected via conductor tracks 33 to the individual plug contacts of a plug 34, the approximately is mounted centrally on the circuit board 30.
  • a U-shaped latching element 35 is fitted onto both edge regions of the printed circuit board 30 and is provided with slots 38 which are offset in relation to one another in both legs 36, 37.
  • the U-shaped latching elements 35 can be snapped onto the edge regions of the printed circuit board 30 with an insulation displacement contact of the conductors 2, the sheathing 12 of the conductors 2 being cut at opposite locations by the edges of the clamping slots 31 such that their metalized surface 32 come into conductive contact with the conductor core 2 'of the conductor 2.
  • FIG. 16 shows a plan view of a U-shaped latching element 35 with the obliquely running slots 38 in the two legs 36, 37, which delimit the inner longitudinal slot 39.
  • the non-stripped conductors 2 are inserted into the slots 38, which are thus at an angle to the longitudinal slot 39 which is plugged onto the edge regions of the printed circuit board 30 provided with the clamping slots 31, as a result of which the insulation displacement contacting takes place.
  • FIG 14 shows the arrangement of the U-shaped locking elements 35 within two housing half-shells 40 which are designed such that the housing formed from the two housing half-shells 40 is closed when the locking elements 35 are pushed onto the edge regions of the printed circuit board 30.
  • FIGS. 17 and 18 show, as a fifth embodiment, a contact element which is formed from a comb-like circuit board 41 and a latching element 42, which is plugged onto the free edge area of the circuit board 41 and is locked behind latching lugs 43 of the circuit board 41.
  • the circuit board 41 is provided in the region of the latching lugs 43 with parallel longitudinal slots 44 at the edge, so that the outer legs 45 of the circuit board 41 cut free as a result are resilient.
  • contact slots 46 are formed in the printed circuit board 41, which are provided with metallized surfaces 47 which protrude into the contact slots 46.
  • the locking element 42 is provided with a longitudinal slot 48 and with transverse bores 49 arranged at an angle for this purpose, into which the conductors 2 are inserted.
  • the sheaths 12 of the conductor 2 are cut from the edges of the contact slots 46, electrical contact being established between the conductor cores 11 and the metallized surfaces of the circuit board 41.
